Abstract: A blower assembly includes a centrifugal fan and a motor assembly. The centrifugal fan has a plurality of axially extending impeller blades, a first axial end, and an air inlet. The air inlet is at the first axial end of the centrifugal fan. The motor assembly comprises a stator, a rotor, and an air directing surface. The air directing surface is shaped and configured to direct air drawn into the air inlet radially outwardly toward the impeller blades. The air directing surface extends generally along the rotor axis from its first end to its second end. At least a surface region of the air directing surface generally circumscribes the rotor axis and diverges radially outwardly as such surface region of the air directing surface extends away from the first end toward the second end.

Abstract: A sensorless permanent magnet motor system that prevents negative torque caused by back EMF. The system determines the position of the rotating permanent magnet by monitoring back EMF generated on an inactive coil of the motor system. A snubber circuit is used to prevent the back EMF from causing negative torque on the motor. The voltage of back EMF used to power a logic circuit, such as a microcontroller, that controls the operation of the motor. The microcontroller controls the operation of the motor by detecting back EMF and is also partially powered by the back EMF.

Abstract: A health monitor circuit for an electric machine is described. The health monitor circuit includes at least one sensor configured to measure a parameter of the electric machine, a communication interface, and a microprocessor coupled to the at least one sensor, the communication interface, and a memory. The microprocessor is configured to periodically collect time samples of the parameter measured by the at least one sensor, transmit factors of the time samples to the memory, and perform a high resolution fast-Fourier transform (FFT) on the factors. The microprocessor is also configured to extrapolate results of the high resolution FFT to a produce a high resolution frequency domain waveform, filter the high resolution frequency domain waveform by a parameter, and transmit, via the communication interface, the filtered frequency domain waveform to a remote system for further processing.

Abstract: A control system is provided for an electric motor configured to drive a fluid moving apparatus to generate a fluid-flow. The control system includes a drive circuit configured to regulate power supplied to a stator of the motor to turn a rotor and generate the fluid-flow, and a processor that computes a value proportional to at least one of a system resistance or a static pressure for the fluid moving apparatus based on a fixed set point for a first control parameter and a feedback parameter. The processor receives a fluid-flow rate demand and computes an operating set point for a second control parameter based on the fluid-flow rate demand and the value proportional to the system resistance or the static pressure. The processor controls the drive circuit based on the operating set point to supply power to the motor and operate the fluid moving apparatus to generate the fluid-flow.
